1. A method for supporting inductive communication, the method comprising:

  • coupling at least one transducer to one of a selected first circuit for transmitting and a selected second circuit for receiving, wherein the at least one transducer is selectively coupled to a transmitter via the first circuit and the at least one transducer is selectively coupled to a receiver via the second circuit;

    if the first circuit is coupled to the at least one transducer, adjusting electrical characteristics of the first circuit to increase a magnetic field generated by the at least one transducer; and

    if the second circuit is coupled to the at least one transducer, adjusting electrical characteristics of the second circuit to increase a signal generated by the at least one transducer.
